The California Independent System Operator (CAISO) has a large amount of battery storage providing electricity during the evening peak. See https://www.gridstatus.io/live/caiso?date=2024-06-23 https://www.gridstatus.io/live/caiso?date=2024-06-23
The amount of storage is set to increase substantially this year.
"Developers plan to add 6,813 MW of battery power storage capacity in CAISO's domain this year, dominated by four-hour lithium-ion resources, roughly double their additions in 2023"

- pyrale 2y agoI mean, 2023 is the worst year in your graph, 2024 data is as of April, when peakload happened in summer every of the last 25 years [1]. There is some interesting data about CAISO batteries, but this graph is not it.

- kieranmaine 2y agoThe blog post it is from provides a more complete picture. https://blog.gridstatus.io/caiso-batteries-apr-2024/ https://blog.gridstatus.io/caiso-batteries-apr-2024/ My understanding of the graphs is they show April for each year.
- pyrale 2y agoYes, my point is load in April, per the blog numbers, seems to be 15-20 GW down compared to yearly peak. Battery buildup is of course going to be more impressive when load is low. The first graph of the article shows batteries peak 2.5 G higher than 2023, which is far from explaining the flattening of gas use. The "battery shifting load" and "Load not including battery charging" graphs tend to show that the big difference from 2023 is to ease the morning ramp down, which is good progress, but much more incremental than what's advertised by the graph you're showing.
- bryanlarsen 2y agoSolar replacing natural gas is far more impressive in April than it is in the summer. Summer with its long days has a lot more solar than cloudy April.
- arnaudsm 2y agoThis is very exciting, California might be the first to pull it off at scale in the future. However it's still 9% of the current MW capacity. We'll see how it ages and it costs in the long run. Most of the pilotable energy sources in the state remain nuke, hydro & fossil fuels. Safety issues, notably fires, notably in Australia's grid are still an issue.
